A pressure transmitter where pressure is applied to one side of the sensor while the other side is open to atmosphere. The transmitter generate standardized output signal representing the measured value.
A physical object that can be any electrical device, usually incorporating an electromagnet, whereby a current or signal in one circuit can open or close another circuit.
A temperature sensing element that operate on the principle of changes in electrical resistance of pure metals (sintered semiconductor material) and are characterized by an almost linear positive change in resistance with temperature.
A rigid vertical or near vertical pipe for the flow of liquid or gas between the seabed and the surface.
A physical object that is a vertical or near vertical pipe for the upward flow of liquid or gas.
A variable area flow meter which consists of a tapered tube of glass with a float inside that is pushed up by flow and pulled down by gravity.
A positive displacement compressor in which compression displacement is effected by the positive action of rotating elements.
A positive displacement pump that consists of a chamber containing gears, cams, screws, vanes, plungers or similar elements actuated by relative rotation of the drive shaft or casing and which has no separate inlet and outlet valves.
A detecting element that is intended to sense rotational speed.
A physical object that is a pressure relieving device designed to burst at a calibrated pressure to prevent pressure in systems or vessels from reaching unsafe levels.
A sample loop adds a predetermined volume to the process.
A physical object intended to be used to collect and contain representative specimens or selections.
A detector intended to detect sand in a fluid.
A manual control switch which has more then two possible positioning states.
A 'device' intended to separate different types of substances.
A tank gauge that is intended to intermittently lower a displacer to measure a liquid level, bottom level, interface level or density.
A tubular heat exchanger in which a tube bundle is surrounded by a shell.
A physical object that is transparent and intended for viewing a vessel or piping system interior.
A detectable transmitted energy (e.g. voltage, current, pneumatic or magnetic field strength) by which information can be transmitted.
An electric signal transducer that is intended to convert one type of standardized transmission signal into another.
A physical object intended to reduce a noise level.
An acoustic device producing a loud sound as a signal or warning.
A slide valve that is equipped with an actuator that manipulates a stream of fluid in the response to a signal from an external sensing element and with input of energy from an external source.
A smart meter is an electronic device that records information—such as consumption of electric energy, voltage levels, current, and power factor—and communicates the information to the consumer and electricity suppliers.
